Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil loading pallet capable of supporting two or more coil arrangements with one pallet.

[0002]

2. Description of the Related Art A coil on which a steel plate or the like is wound is placed on a coil loading pallet by a crane, and the AGV (Au
Tomatic Guided Vehicles) are used to move and manage the pallet as a unit. In consideration of the space occupied by the site and the like, it is desirable to mount the coils in one row or in two rows on this type of coil loading pallet.

Therefore, conventionally, the following techniques have been used.

[0004] Prepare various pallets for one row, two rows, etc. and use these pallets appropriately.

.. One-row or two-row coil receiving members are detachably provided on the pallet, and these coil receiving members are exchanged with a crane and used properly.

[0006] A coil receiving member is movably provided on the pallet, and the coil receiving member is manually moved by a worker to switch between the one row and the two rows.

[0007]

However, since the number of pallets and the number of pallets are increased, a large site is required as a pallet storage area, which is not efficient. However, since the crane is used to attach and detach the coil receiving member, the crane carrying capacity is reduced. However, it takes time because of manual operation, and the crane carrying capacity decreases.

An object of the present invention, which was devised in view of the above circumstances, is to provide a coil loading pallet in which the placement of coils to be automatically placed can be switched by utilizing the weight of the coils.

[0009]

In the coil loading pallet according to the present invention created in consideration of the above circumstances, the moving coil receiver provided on the pallet body is moved to change the coil arrangement. In the above pallet for coil loading, the pallet body is provided with a moving means for moving the moving coil receiver by the load of the loaded coil. Further, the pallet body may be provided with return means for urging the moving coil receiver in the direction opposite to the moving means.

According to the present invention, since the moving coil receiver is moved by utilizing the load of the coil and the arrangement of the coils to be loaded is switched, the power can be switched completely automatically without any other power. . That is, since the crane is not used to move the moving coil receiver, the crane carrying capacity does not decrease. Further, since one pallet can handle two or more coil arrangements, the number of pallets can be reduced to less than half that of the conventional one, and the site in the factory can be effectively used for other purposes.

More specifically, the present invention relates to a pallet body,
When a pair of fixed coil receivers are provided at predetermined intervals and a pair of moving coil receivers are movably provided between the fixed coil receivers, and a coil is loaded on the moving coil receivers between the movable coil receivers. A moving means for receiving the load of the coil to separate the moving coil receivers from each other is connected, and usually a returning means for connecting the moving coil receivers to each other is connected between the moving coil receiver and the fixed coil receiver so that the moving coil receivers come close to each other. Consists of

The moving means includes a coil receiving beam for receiving the load of the coil, a first rope having one end connected to the coil receiving beam and the other end connected to the moving coil receiver, and wound around the first rope. A second rope which is composed of a hung dynamic pulley and a first weight hung from the dynamic pulley, and wherein the return means is connected to the moving coil receiver and a second rope provided at an end of the second rope.

Specifically, as shown in FIG. 6, sheaves (or chain wheels, etc., the same applies hereinafter) 7 and 8 are provided at predetermined intervals on the pallet body, and ropes (or chains, etc., are the same hereinafter) are provided on the sheaves 7, 8. ) 9 is wound endlessly. The bracket 10 of one moving coil receiver 6 is connected to the upper rope, and the bracket 11 of the other moving coil receiver 6 is connected to the lower rope. According to this structure, when the rope 9 goes around, the moving coil receivers 6 and 6 interlock with each other in accordance with the direction of the rope 9 to move toward and away from each other.

The sheaves 7 and 8 are, as shown in FIG.
The pallet body 1 is arranged at both ends of the moving coil receiver in the longitudinal direction, and the sheaves 7, 7 at both ends thereof are arranged.
And 88 are connected via the long shaft 12 (see FIG. 7). As a result, the ropes 9 and 9 wound around the sheaves 7 and 8 are tuned to each other, and the skew of the moving coil receiver 6 is prevented.

As shown in FIG. 9, each moving coil receiver 6 is provided with a meshing portion 13 formed in a concave-convex shape at a portion where the moving coil receivers 6, 6 come into close contact with each other.
As shown in FIG. 2, the meshing portion 13 serves as a stopper for the moving coil receiver 6 when the coil C is loaded between the moving coil receiver 6 and the fixed coil receiver 5. As shown in FIGS. 3 and 5, each moving coil receiver 6 is provided with a stopper portion 14 at a portion where the moving coil receivers 6 and 6 are separated from each other and contact the fixed coil receiver 5.

As shown in FIGS. 1, 4 and 5, each moving coil receiver 6 has a coil C to be stacked when one coil C is stacked between the moving coil receivers 6 and 6. A moving means 15 for moving the moving coil receivers 6 and 6 away from each other by a load is connected. The moving means 15 has a coil receiving beam 16 which receives the load of the coil C, and one end which is connected to the coil receiving beam 16 and the other end which is the moving coil receiving member 6.
A first rope 17 connected to the first rope 17, a moving pulley 18 wound around the first rope 17, and a first weight 19 suspended from the moving pulley 18.

More specifically, as shown in FIGS. 1, 4 and 5, the pallet body 1 is provided with collars 21 at both ends in the longitudinal direction of the moving coil receiver 6 via brackets 20. A slide rod 22 is inserted through each collar 21. The coil receiving beam 16 is stretched over the top of the slide rod 22 via an L-shaped member 23. As shown in FIGS. 4, 5 and 7, the coil receiving beam 6 receives the load when the coil C is placed between the moving coil receivers 6 and 6 when the coil C is in contact with the moving coil receivers 6.

A flange 24 is provided at the bottom of the slide rod 22.
Is provided, and the first rope 17 is connected to the flange 24. The first rope 17 is the bracket 2 described above.

It is wound around the sheave 28 provided on the No. 1 and connected to the moving coil receiver 6. According to this configuration, when the load of the coil C is applied to the coil receiving beam 16, the slide rod 22 descends and the first rope 1
7, the moving coil receivers 6 and 6 are separated from each other.

At this time, as shown in FIG. 5, the slide bar 22 is dimensioned so as not to project below the pallet body 1. This is so as not to disturb the traveling of the AGV3. That is, the installation position of the slide rod 22 is set higher by the bracket 20 in anticipation of the descending amount of the slide rod 22.

Further, the pallet body 1 is connected with a returning means 29 for moving the moving coil receivers 6, 6 in the opposite direction to the moving means 15. The returning means 29 includes a second rope 30 connected to the moving coil receiver 6, a second weight 31 provided at an end of the second rope 30, and a constant pulley 32 wound in the middle of the second rope 30. When the load of the coil C is not applied to the coil receiving beam 16, the moving coil receivers 6 and 6 are brought close to each other.

More specifically, a second weight 31 is connected to the moving coil receiver 6 via a second rope 30. An intermediate portion of the second rope 30 is wound around a constant pulley 32 (sheave) provided on the pallet body 1. According to this configuration, normally (when the load of the coil C is not applied to the coil receiving beam 16), each moving coil receiver 6,
6 are pulled by the second weight 31 and come close to each other as shown in FIG. 4, and the coil C is loaded between the moving coil receiver 6 and the fixed coil receiver 5 as shown in FIG.

As shown in FIG. 10, each of the moving coil receivers 6 and 6 has wheels 34 that travel on rails 33 laid on the pallet body. A spring 35 is provided between the wheel 34 and the moving coil receiver 6. The spring 35 floats the bottom surface 6x of the moving coil receiver 6 from the upper surface 1x of the pallet body 1 when the load of the coil C is not applied to the moving coil receiver 6, and moves the moving coil receiver 6 when the load of the coil C is applied to the moving coil receiver 6. Receiving bottom 6x
Is placed on the upper surface 1x of the pallet body.

As a result, the moving coil receiver 6 has the coil C on the coil receiving beam 16 as shown in FIGS.
When it is in contact with the rail 33, the rail 33 travels smoothly on the rail 33 (at this time, the load of the coil C is not applied to the moving coil receiver 6), and as shown in FIGS.
When the load is applied, the spring 35 contracts and the load of the coil C is applied to the pallet body 1. Therefore, coil C
The weight of the wheel 34 does not damage the wheel 34.

The operation of this embodiment having the above configuration will be described.

Normally, in a natural state (a state in which the load of the coil C is not applied to the coil receiving beam 16), the moving coil receivers 6 and 6 are pulled by the second weight 31 as shown in FIG.
Comrades are close. Therefore, in this state, as shown in FIG. 2, a gap between the moving coil receiver 6 and the fixed coil receiver 5 is 2
A row of coils C is loaded. At this time, the meshing portion 13 serves as a stopper (see FIG. 9).

When one row of the coil C is loaded between the movable coil receivers 6 and 6, the coil C is arranged as shown in FIG.
Hang down the crane with a crane to lower the coil receiving beam 1
Press on 6. Then, due to the load of the coil C, as shown in FIG.
As shown in FIG. 7, the coil receiving beam 16 is pushed down, the slide rod 22 descends, pulls the first rope 17, and the moving coil receivers 6 and 6 are separated from each other. At this time, the moving coil receiver 6 is floated from the pallet body 1 by the spring 35 as shown in FIG.
This allows the rail 33 to travel smoothly.

When the moving coil receiver 6 comes into contact with the fixed coil receiver 5 and stops, the load of the coil C is applied to the moving coil receiver 6. Then, the spring 35 contracts, and the moving coil receiver 6 lands on the pallet body 1 to support the load. This makes it possible to achieve both smooth movement of the moving coil receiver 6 and stable support of the coil C by the moving coil receiver 6. When the diameter of the coil C is small as shown by the alternate long and short dash line in FIG. 5, the coil receiving beam 16 further descends, but the descending amount is absorbed by the rising of the first weight 19 and the movable pulley 18.
